9.9.2

Hi-Z PWM_SIG Outputs (HiZPSig)

Default = 0

Function:

When cleared, the PWM_SIG1 and PWM_SIG2 output drivers are placed in a high-impedance state.

When set, the PWM_SIG1 and PWM_SIG2 output drivers are active. It should be noted that the function

of the PWM_SIG outputs is determined by the PWMDSel[1:0] bits in Register 04h.

9.9.3

Bass Cross-Over Frequency (BassMgr[2:0])

Default = 000

Function:

Controls the operation and cross-over frequency of the bass manager. See “Bass Management” on

page 35 for more information.

9.9.4

Enable Channel B Parametric EQ (EnChBPEq)

Default = 0

Function:

Enables the parametric EQ bi-quad filters for channel B.

9.9.5

Enable Channel A Parametric EQ (EnChAPEq)

Default = 0

Function:

Enables the parametric EQ bi-quad filters for channel A.
